To all wtomfit muy# concor;

zen of the United Statesiresiding Wellson, county of Jacksonfand'tate ofGhio, have invented certain new and useful lin;- provements inBovwFacingOars, or which f the following is a specification.

My invention relates'to rowing .devices ory oars and particularly to-'that class thereof'4 known as bow `facing oars.

'The `objectofiny invention isv to provide Aan improved device of theclass mentioned Wherebythe oarsman may face the bow of the boat and atthe same time propel the boat with the saine stroke as used with the Afurther object of my invention is to provide a device of the classmentioned which maybe readilysecnred by any one to. the gunwaleof'agbo'atj without thel use of tools and irrespective'ofv the curvatureof the gnnwale at'the place of attachment.

Other objects will appear hereinafter.

With these objects inview my invention consists generally inr ahousingcomprising apair of parallel-'substantially horizontal plates, apair of intermeshing segment gears Y rotatablylrnounte'd between theplates and each provided with a socket to receive the Shanks of the oarblade and. handle' respec- Y. tively, and a pair of bracketsviswiveledbe tween the plates of the housingand provided V3 with clampsfor engaging the gun'wale t' lily invention further consists in variousdetails of construction and arrangements of parte all as will 'beullydescribed hereinafter and particularly pointed out' in' the- Myinvention will bernore readily under stood by reference to theaccompanying drawings forming a. part of this specifica-4 tion and inwhich- Figure l is a tcp plan view of a rowing device embodying myinvention in its preferred. form, a portion of the top plate of thehousing being broken away, 2 is a vertical longitudinal section onsnbstan tially the line of Fig. l, and Fig.- 3 is a transverse sectionon the line oi" Fig. L

Referring new to the drawingl and 2indicate the upper and lower platesrespectively which form the housing, These are arranged substantiallyhorizontal and n allel and are preferably provi 'ned .i with roundedends 3. ltotatably mount t' Be 1t known that I, Dimmi, Donn, a c1ti. b

vto receive the Shanks 9v upwardly etween the plates l and 2 upon pinsor .rivets al which serve to secure said plates tois a pair ofinternieshing segment' gether,' gears 5 and 6, each provided with aradially extending stem 7 terminating inA a. socket 8 and 10 of the oarblade and handle respectively.

' In orderto attach Vthe housing and the contained nieclianisinto thegunwale of the boat l provide the saine withr a pair of brackets eachformed with a clamp to' engage the gunwale, and inl order that thevdevice may be readily secured to the side of any row boat irrespectiveof the curvature of the gunwale l pivotally connect clamps to thehousing. To this "end each bracket comprises a. blockv l1 swiveledbetween the plates l and 2 at the sides thereof7 upon pins l2, and aclamp lrconnectcd thereto. To permit the oar to be raised a d lowered inthe ordinary manner, l prefer to swivel the block 1l 'upon the clamp 13so that the housing and mechanism may readily turn upon a horizontaltransverse axis. Accordingly,

proJecting. ear or lugl/l and the block 1l is formed with a horizontallypro- 5V swiveled in the ear 1li, as

shown; clearly in Fig. 3. To facilitate at 'tachingithe device to the'gunwale A the g 'pair'of' dependingV members ltiadaptedv to embrace thegunwale clamps'are 'formed of a and vthreaded through onel of seidmembers is a' thumb screw 17.

'The inanner of attaching the device to the boa-t and of operating'thesame is obvious and does not need detail. description.V

Having thus described my invention what l'yclaiin as new and desire tosecure by' Letters Patent is :'-1

l, ln a device'. of the class described, a housing comprising a pair ofparallel substantially horizontal plates, .a pair'of in# termeshingsegmentv gears rotatably mount; ed between said plates, sockets formedon said gears? to receive the Shanks of an oar blade and handlerespcctively, a pair of brackets swiveled between the plates of saidhonsingto lturn upon a vertical clamps formed on 'said tially asdescribed, Y

2. ln a device of `the class described, a housing comprising a pair oiparallel suhstantially horiZorngal"plates3 a pair of brackets,substaneach clamp 13 is formed with an" aXis,. and 211% l termeshingsegment gears rotatably mounted between sind plates, sockets Xecl tosaid gears to receive the Shanks of an oar blade and. handlerespectively, u pair of blocks swveled between the plates et the sides'thereof and each providedv with a horzon telly extending pin, clampsadapted to be secured to the gunwale of a boat and formed with upwardlyextending ears, said pins be' ing swiveled in said ears, substeltiallyes 10 described.

In testimony whereof I have signed my name to this specification in. thepresence of two subscribing Witnesses.
